baking enamelled products and in baking and glazing clay products.

The conveyers in passing from one department to another are necessarily passed at times through tunnels while at other times they are overhead a sufficient distance so as not to interfere or obstruct the work of the department through which they are passing. This method makes effective lubrication exceedingly difficult. The conveyers employed so in the baking industries are subject to intense heat and for this reason are not accessible for lubricating purposes. Lubrication by grease cups under heated conditions is highly unsatisfactory for in the'conditions recited it 2 is practically impossible to operate the grease cups.

The present invention has as a further object the lubrication of the conveyer trolleys under the adverse conditions recited. The lu-- bricant is supplied from containers which are placed at suitable intervals upon the suspended trolley rail. A novel feeding mechanism is provided, consisting of brushes satu' rated with a lubricant supplied from the containers and adapted to be wiped by spouts attached to the trolley, the lubricant passing from the spouts tothe bearings of the trol leys, the motion of the conveyer supplying the lubricant and the only manual operation being the filling of the lubricant containers.

With these objects in view the invention consists essentially of the elements to be more particularly disclosed in the following description with reference to the accompany 4 ing drawings, in whichsage to the bearings; and

Serial No. 284,252.

Fig. 3 is a plan view of the lubricator sup port with the container members removed.

Similar characters of reference are employed to designate the corresponding parts throughout the different views.

The numeral 1 designates the I-beam trolley rail which is conveniently suspended and upon which is mounted a bracket 2, attached by means of bolts 8. The bracket 2 carries a pivot bolt 4 upon which is mounted the pivoted forkmember 5 being. formed with an extension 6 which carries a downwardly extending bolt 7, for retainingthe coil spring 8. The spring 8 bears upon the upper surface of the trolley rail and holds the fork member 5 resiliently in a horizontal position.

Formed integral with the fork member 5 is the downwardly curved arm 9 which is formed with a head 10 to which is bolted a cap member 11, the head 10 and the cap 11 be ing suitably grooved on their inward faces for securing a brush 12 directly under the outlet 13 of the lubricant container 14 which is retainedin the bore 14' of the forked arm 5. The brush 12 is constructed with a central tube 15 through which the lubricant passes to saturate the bristles of the brush.

The trolley wheels 16 are supported by a pair of arms 17 forming a fork to which are attached the studs 18 which are provided with the central bores 19. The rims 20 of the trolley are supported by the bearings 21, the bearings being in suitable bearing races formed upon the studs 18. Oil receiving cups 22 project upwardly from the studs 18 and are connected at their lower ends to the interior bores 19, the bores 19 forming a passage from the spouts 22 to the bearings 21.

The link member 23 is sandwiched between the lower ends of the members 17 and is attached by the bolts 24, and extends downwardly to be connected by the propelling chain 25. At '26 is provided the means for connecting the saggers or baskets for carrying the load.

In operation the trolleys 16 are propelled along the trolley rail 1 by means of the chain 25 until they come under the lubricant containers. Thelubricant has been slowly fed by any suitable mechanism through the outlets 13 into the tubes 15 of the brushes, the bristles of which are thereby saturated with the lubricant. The receiving cups 22, which have enlarged bell mouthed ends, Wipe a quantity of the lubricant from the bristles of the brush. The lubricant passes through the rgceiyi cups 2? into the central bores 19 of theflu s 18 supporting the trolleys and from the bores 19 it asses to the bearings 21 1. which are thereby e ectively lubricated.

In trolley conveyersofconsiderable length, and in conveyors subject to great heat, the amount of lubrication necessary is variable and may be accommodated by placing a series of lubricating mechanisms'at desired intervals .u on the trolley rail.

Al bugh a specific embodiment .of my invention has been disclosed it will be understood that such variations in the details of 2 construction may be made as fall within the sea e of the appended claims.
